　　7-zip now creates multi-block xz archives by default. Block size can be

　　specified with -ms[Size]{m|g} switch.

　　xz decoder now can unpack random block from multi-block xz archives.

　　7-Zip File Manager now can open nested multi-block xz archives

　　(for example, image.iso.xz) without full unpacking of xz archive.

　　7-Zip now can create zip archives from stdin to stdout.

　　7-Zip command line: @listfile now doesn’t work after – switch.

　　Use -i@listfile before – switch instead.

　　The BUGs were fixed:

　　7-Zip could add unrequired alternate file streams to WIM archives,

　　for commands that contain filename wildcards and -sns switch.

　　7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.

　　7-Zip 17.00 beta ignored „Use large memory pages“ option.
